Abstract

Method and device for separating a fine-grained solid into a fine material and a coarse material at a separating grain size below 50 mu m, preferably below approximately 10 mu m. The aim of the invention is to indicate a method and a device which, in an economical manner, make possible a clear separation in particular in the grain size range below approximately 10 mu m. To achieve this aim, the fine-grained solid is dispersed in a liquid which can form drops and the dispersion is forced into a defined sink flow with a superimposed rotation flow generated independently of the sink flow. The ratio of the speeds of the sink flow and the rotation flow determines the separating grain size. Serving as the device is a rotary-driven deflector wheel with blades running parallel to its axis of rotation and forming flow ducts, which is flowed through from the outside to the inside and to which the solid dispersion is fed at the external circumference. <IMAGE>
